If the Prefix allocation mode is selected (as described below), then the Winner Series BRI
Gateway checks the prefix of the outgoing numbers, and dispatches phone calls through the
appropriate SIM. This helps ensure the lowest call rate possible for the user.
6.4. PORT ALLOCATION MODE SETTINGS
The manner in which a phone call is directed to a port is determined in this frame.
By Prefixes: if selected, then the Winner Series BRI Gateway directs a call through a port
according to the defined prefixes table.
Maximum prefix length is how many digits the prefix could be.
Waiting time of free port is how many seconds the BRI will wait for the port when busy.
If one GSM network is designated for both ports, then select the manner in which ports will be
selected:
Cyclic indicates that ports will be selected in a cyclic manner: for example, if the first call is via
port 1, the following call will be directed through port 2, the third call will be directed through port
1, and so forth.
Random indicates that ports will be selected at random, for example: port 2, port 2, port 1,
port 2, port 2, port 1, port 1, and so forth.
If Static is selected, each ISDN B channel (and its respective telephone) is linked permanently
to a port as defined in the prefixes table frame.
An ISDN B channel (and its respective telephone) can be switched as described below.
